Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643524, here are decompositions:

3 + 8643521 = 8643524
37 + 8643487 = 8643524
67 + 8643457 = 8643524
157 + 8643367 = 8643524
181 + 8643343 = 8643524
313 + 8643211 = 8643524
433 + 8643091 = 8643524
577 + 8642947 = 8643524

Showing the first eight; more decompositions exist.
